They can be categorised into various forms including chelating resin
, adsorbent resin, mixed bed resin, etc.

O ne method would be to use a chelating resin
that can remove the dissolved ions, but this would also increase cost (due to the addition of additional equipment) and cause the removal of chromium ions at the same time.
The synthesized resin was applied for adsorption of nickel (II) ions comparing with the conventional DTOF chelating resin
. The parameters affecting adsorption process as initial pH, agitation period, sorbent dosage, and initial concentration of Ni(II) ions were studied.
1989), or through capture of the positively charged unbound Al species on a cation-exchange or chelating resin
A buffered sample is loaded onto a column packed with an appropriate cation exchange chelating resin
. The anions pass through the column unretained while many of the cations are retained.
Polystyrene chelating resin
with imidazolylazobenzene functional###Pb(II)###0.25
The chelating resin
preconcentration method has excellent analytical features of nonselective multielement determination for many trace elements in seawater, along with efficient removal of matrix elements such as Na, K, Ca, and Mg [5-10].
Similar results were obtained with previous study with chelating resin
In this work, chelating resin
was prepared by chemical attachment of the chelating moiety, 4-(2-pyridylazo)resorcinol(PAR) onto silica gel using an eco-friendly chemical transformation.
Adsorption is widely used, especially in the surface with a chelating moiety of the chelating resin
. During the past two decades, the use of chelating resin
for metal ion preconcentration and separation has been considerably increased [l-5].
